The utility model discloses a magnetic core structure of a shielding type solenoid coil. The magnetic core structure of the shielding type solenoid coil is characterized by being provided with an annular wire spool (1), N supporting arms (2) are evenly distributed on the annular wire spool (1), one ends of the N supporting arms (2) are gathered at the circle center of the annular wire spool (1), the other ends of the N supporting arms (2) extend in the radial direction of the annular wire spool (1) to form N free ends, a wire passing hole (3) is formed in the center of the position where the N supporting arms (2) are gathered, and the free end of each supporting arm (2) is provided with a downwards concave winding groove (4). The magnetic core structure of the shielding type solenoid coil has the remarkable effects that the advantages of an integrated coil and the advantages of a disc type coil are integrated, the grade of transmission power is increased, leakage flux between mechanisms is reduced, and on the premise of ensuring the grade of transmission power, the charging area of an electromagnetic coupling mechanism is enlarged, and electromagnetism exposure is reduced at the same time.
